Housed in a Group 31 enclosure that fits standard battery trays across countless vehicles, the XS Power SB1000-31 brings 12V ultracapacitor technology to car audio builds where installation simplicity is as important as raw performance. The farad capacitor bank delivers 1,000 farads of near-instantaneous energy storage, acting as the fastest power source your amplifiers have ever had access to.
Standard Tray, Uncommon Performance
Whether you are competing at SPL events or building the cleanest-sounding daily driver on the block, this high current capacitor bank eliminates the voltage sag and headlight dimming that rob your system of its best performance. The SB1000-31 pairs naturally with an existing AGM battery to form a complete power solution — battery for sustained output, ultracapacitor for instantaneous transient demand.
